Grave MercyRobin LaFevers HMH Books for Young Readers

A strange birthmark spares Ismae from an arranged marriage with a cruel man, but thrusts her into the power of the sisters at the convent of St. Mortain. There, Ismae discovers she’s been gifted with great power. To understand her potential, she must embrace the training offered by the mysterious sisters. If Ismae agrees, they will teach her the arts of murder and seduction, so that she can be sent out into the world to bring the justice of an old god: Mortain, the god of death. When an opportunity arrives for Ismae to serve the young duchess of Brittany who faces an arranged marriage of her own, Ismae can’t help but accept, remembering her own past.
